See this file. 

 

The original data can be seen in the Edit Query view. Click the gear icon of the SOURCE step. 

 

It brings the table in in the desired format according to your image. 


It is usually better to do this kind of thing in Power Query as it can more easily manipuilate tables and compare columns.
